The thing that Castillo, De Genaro, (Fabi and a Russian whose name I can't recall) have that Akoz is a little behind in is aura. With those other four I really get the impression they are in charge of the floor. With Akoz, not as much. That doesn't mean she doesn't play just as well, it's just an impression.
castillo owns the floor too much. she is sometimes too aggressive and frenetic. she often takes the ball from her setter (marte in the NT, maybe not so much in the clubs, depending on the setter) and then overshoots the set ...
